VTAM independence enables IBM® Connect:Direct® to initialize without SNA support. It also enables IBM Connect:Direct to continue functioning if VTAM is not available, and to reattach to VTAM when it is restored.
To use VTAM independence, you must specify SNA=YES in the initialization parameters. You must also specify a valid VTAM APPLID in the network map local node record.
If SNA= YES is specified in the initialization parameters and you try to start IBM Connect:Direct when SNA is not available, or if SNA becomes unavailable during a session, the system prompts the operator for action.
See SNA = YES | NO for more information about the SNA initialization parameter. See API Signons for more information about operator actions.
